What types of cliques have you come across in fiction, what types of people are in that particular clique?
Pretty much the stereotypical types, like in the movie Mean Girls. Emos are with emos. Jocks with jocks. Nerds with nerds. Outcasts with outcasts. That kind of thing.
Though in real life, this doesn’t necessarily happen. I have seen emos and jocks together, nerds and cheerleaders, and everything else happen. Anyone can be together, as long as they have common interests and are nice to each other.
